After an ear-bending from Marsha Harris, Supt. Chandler is determined to bring to an end the one-boy crime wave on the Larkmead Estate caused by resident hooligan Peter Rogers. Chandler persuades Sgt. Ackland to talk to Peter's mother, and also tries to get Marsha Harris's daughter Cassie to make a statement to the police against Rogers, but both are too scared of the boy to comply. When Cassie Harris is found half-drowned in a river, and PCs Stamp and Hollis turn up a CCTV tape of Rogers smashing up cars, it seems they may be able to put him away at last - although it turns out that Cassie's drowning was self-inflicted and the CCTV tape is actually Peter's brother Gavin trying to frame him for criminal damage.
